Description

Technical Field

[0001] The utility model relates to the field of fastener processing, in particular to an automatic fastener bending device. Background Art

[0002] Fasteners are a type of mechanical parts used for fastening and connection and are extremely widely used. Fasteners are widely used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc. Various fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments and supplies, etc. They are the most widely used mechanical basic parts.

[0003] During the processing of existing fasteners, the raw materials need to undergo a series of processing, including bending the raw materials, which requires the use of corresponding bending devices. In actual use, the existing bending devices place the raw materials in the bending mechanism, and the upper pressing block presses down on the raw materials, so that the forming mechanism that affects the shape limits it, thereby realizing stamping and bending forming. However, in actual operation, since the raw materials are prone to falling debris during bending, the debris will adhere to the forming groove of the pressing block or the forming block, and repeated pressure and bending will cause the debris to be pressed on the surface of the bending part, thereby affecting the quality of the fasteners. At the same time, the bent raw materials are easily stuck in the forming groove or the forming block, making it difficult to remove. For this reason, it is necessary to design a new technical solution to solve this problem. Utility Model Content

When performing a bending operation, the raw material is placed on the top of the forming mechanism, and then the first electric push rod is started to drive the pressing block to descend, so that pressure can be applied to the raw material to make it bend and form. After bending, starting the second electric push rod can drive the scraper to move, so that debris on the lower surface of the pressing block can be scraped off and fall onto the surface of the forming mechanism. In addition, the scraper located on the lower side can push the debris to move outward, thereby realizing the cleaning function and preventing the debris from being pressed on another fastener.

When the pressing block descends to apply pressure to the raw material for bending and forming, the forming block will descend under pressure, thereby compressing the spring under the guiding action of the plug rod, thereby achieving a buffering protection effect and extending the service life of the device.

[0010] Preferably, a forming groove adapted to the pressing block is provided on the top of the forming block, and the pressing block and the forming groove can be used to accurately pressurize and bend the raw material.

[0011] Preferably, a first limiting rod is fixed at the middle of the top of the pressing block, and the first limiting rod movably runs through the top plate.

The outer wall of the movable plate 21 is provided with scrapers 23 fixed on the upper and lower sides.

[0026] Specifically, when performing the bending operation, the raw material is placed on the top of the forming mechanism 5, and then the first electric push rod 62 is started to drive the pressing block 61 to descend, so that the raw material can be pressed to be bent and formed. After bending, the second electric push rod 22 is started to drive the scraper 23 to move, so that the debris on the lower surface of the pressing block 61 can be scraped off and dropped onto the surface of the forming mechanism 5. In addition, the scraper 23 located on the lower side can push the debris to move outward, thereby achieving a cleaning function and preventing the debris from being pressed on another fastener. At the same time, when the material after forming is stuck, the scraper 23 can play a pushing effect, so that the material can be quickly removed;

[0027] Furthermore, a first limiting rod 63 is fixed at the middle of the top of the pressing block 61, and the first limiting rod 63 movably penetrates the top plate 3. The setting of the first limiting rod 63 can limit the pressing block 61 when it is lifted or lowered, thereby ensuring the stability of the lifting or lowering;

After bending, the second electric push rod 22 is started to drive the scraper 23 to move, so that the debris on the lower surface of the pressing block 61 can be scraped off and fall into the forming groove 53 on the surface of the forming mechanism 5. In addition, the scraper 23 located on the lower side can push the debris in the forming groove 53 to move outward, thereby realizing the cleaning function and preventing the debris from being pressed on another fastener.
